ELECTRICAL CRAFT HELPER PRACTICE CERTIFICATION
SCRIPT 2026 QUESTIONS WITH SOLUTIONS GRADED A+
● Molecule. Answer: Smallest parts of substance can be physically divide into two compose
more Atoms. A molecule is a collection of atoms held together by strong forces called
chemical bonds.
● Atom. Answer: Fundamental constituents of matter. The elements wich come together in
various combination to form molecules of many substances
● Nucleus. Answer: The center portion of an atom which has a positive electrical charge
● Proton. Answer: Single positive electrical charge located in the middle of an atom.
● Electron. Answer: Single negative electric charge orbits around the nucleus some and
Paths close to the nucleus others and Paths varying distance from the nucleus
● Coulomb. Answer: Certain quantity of electrons. The unit of measure that specified the rate
at which electric current flows per second
● Bound Electrons. Answer: Those electrons in orbit nearest the nucleus, not Easily
dislodged from their normal orbit.
● Free electrons. Answer: Those electrons in orbit farthest out from the nucleus, loosely
bound and migrate from one atom to another.
● Valance Electron. Answer: A single electron or one or two or more electrons in the outer
shell of and atom that is responsible for the chemical properties of an atom
● Shells. Answer: Any of the space occupied by the orbit of a group of electrons of
approximately equal surrounding the nucleus of an atom
● Static electric charge. Answer: Electric charge at rest Caused by friction of materials, where
a a surplus of electrons exists and may be discharged.
● Electron flow. Answer: The condition where the free electrons are cause to move in the
same direction along or through a conductor
